CoboCali
OP Update: coming back to this post with a closing update it for any future owners that have a similar fate. In the end I trusted the repair to my insurance-recommended bodyshop, despite them not being a Cali expert in anyway. 9 weeks wait, plus many new parts inc a full roof panel, and they outsourced the new fabric bellow fitment to an auto-trimming specialist. I am more than pleased with the end result, and indeed their communication throughout the process. A v good result from my viewpoint. All is well that ends well.
